Round the mmHg readings to the nearest whole number. Round the kPa readings to the nearest tenth. Round the atm readings to the
1 answer:
The pressure of 2.29 atm can be converted to
Conversation is a way of writing a value in another unit, it helps to reduce large values by using a unit.
It should be noted that 1 atm. =760.0 mm Hg
We were given 2.29 atm, the we can convert it to mm Hg. as;
= 1740.4 mm Hg.
Therefore, The pressure of 2.29 atm can be converted to

Explanation:
Hello there!
In this case, since the formation of water from hydrogen and oxygen is:
Whereas we find a 2:2 mole ratio of hydrogen to water. In such a way, by using the Avogadro's number, the aforementioned mole ratio and the molar mass of water (18.02 g/mol), we obtain the following grams of water product:

Heat energy released : 167.2 kJ
<h3>Further explanation</h3>Heat can be calculated using the formula:
Q = mc∆T
Q = heat, J
m = mass, g
c = specific heat, joules / g ° C
∆T = temperature difference, ° C / K
m = 2000 g
c = 4.18 J/ g ° C
∆t = 20 ° C
